HOISTING APPARATUS.

SPECIFICATION' forming part of Letters Patent N o. 785,641, dated March 21, 1905. Application filed November 22, 1902. Serial No. 132,462.

To all w'bom/ t NM1/y concern:

Be it known that I, JOHN C. SLocUM, a citizen ofthe United States, residing at Columbus,

in the county of Franklin and State of Ohio,

have invented certain new and useful Improvements in Hoisting Apparatus, of which the following` is a specification, reference being had therein to the accompanying drawings.

Figure l is a vertical central section of a hoisting apparatus embodying my improvements. Fig. 2 is a section showing the inlet and exhaust d ucts and ports. Fig. 3 is a view, partly in end elevation, partly in section, ot' themotor-chamber, the face-plate or casingplate being removed. Fig. 4 shows, partly in section, partly in elevation, the gearing-chamber, the end plate at that end being removed. Figs. 5, 6, and 7 show details. Fig. 8 is an end view of the cylinder of one of the motor elements. Fig. 9 is a front elevation of a hoisting apparatus embodying my improvements. Fig. lO is a view or' one end; and Fig. 11 is a view of the same end, the apparatus being shown rotated ninety degrees.

In the drawings, A represents as a whole the rope-winding or drum mechanism; B B, the parts which serve as a framework-support and casing for the operative parts; C, the crank-shaft or main shaft of the mechanism; D, a set of gearing; E, the motor, and F the brake mechanism. With respect to each of these parts or sets of parts I prefer to employ such as are shaped and related substantially as are those shown, but at the outset state that it must be understood that with respect to each of them there can be modifications or variations in many respects without departing from the essential features of the invention.

That part of the mechanism which is indicated as a whole by A, it being the part to which is directly attached the winding-rope and around which the latter is Wrapped, consists of the cylindrical peripheral wall part at a, the end iiange a, the end flange a2, having a gearing-ring a3, together with hubs A A2 at the center, the peripheral parts being' connected with the hubs by webs or .spoke-like portions A3.

The elements oi' the structure which serve as a support or frame and also preferably as a casing or housing' and, as aforesaid, indicated by B Bl are illustrated as being constructed as follows: At one end the part B is formed with a radial web or plate which has a hollow journal at Z2' and a peripheral (approximately cylindrical) wall b2. The radial wall B and the journal provide a support for the hub A of the winding-d rum. The peripheral part b2, as shown,is preferably so constructed as to furnish the supply-chest, (for steam or similar agent,) the feed-ports, the exhaust-duct, and the exhaust-passage for the motor.

The motor here illustrated is ofi the threecylinder trunkengine class. Each of its component elements is indicated by E. It has the cylinder proper,e, with the end e closed, except at the portway c2, the other end, e3, being open. It is provided with a piston e4 and a piston-rod c5, which is connected to the eye or eyes e, by which it is hinged to the wristpin 0 of the crank-shaft. The engine-cylinder is hinged at its outer end, the wall at e' at said end having an enlargement of metal at e7, wherein are formed sockets es, which are fitted to trunnions ci. The cylinder can vibrate around the axis of the trunnion-hinge e. The portway e2 communicates with a feed-port 63 and with the exhaust port b* alternately. In the peripheral rim-wallet1 the frame or casing or housing section B there is an annular chest or duct b5, into which steam or -similar agent (for many `purposes compressed air) is admitted, and at b there is a duct or passage-way for the exhaust. The ports b3 communicate with the feed chest or passage b5, and those at 1 communicate with the exhaust-duct br. The journal portion at e7 is fitted into a cavity 57, formed in an enlargement bg in the casing-wall at the places Where the ports b3 L* are formed. The journal part e7 of the cylinder oscillates in this cavity, to which it is snugly fitted, it being turned to such position as to cause the port c to register with the feed-port 3 and then to register with the exhaust-port b4. The three motor elements E are similar to each other, each being one hundred and twenty degrees of a circle distant from its neighbor. The part at B2 is in the form of a disk or circular plate capable, first, of closing the motor-chamber; second, of furnishing support for the motor elements, and, third, of securingin place the whole structure (or one end thereof) upon an outside frame or abutment, suoli as shown at G. It is bolted to the peripheral wall 52 and, as aforesaid, carries one of the trunnion hinges or pivots e. for each engine-cylinder. It also carries the flanges at B"i or equivalent means for bolting the whole apparatus to the aforesaid frame or similar holder G.

Passing to the other end of the winding device, there is a framing and housing element at B, as aforesaid. It has a wall-section 71., which at the center supports a hollow journallike part /t and is also connected to a peripheral (preferably cylindrical) wall h2.

if is an extension from the journal or bearingI /t and intended for supporting some of the gearing, as will be described.

7a4 is a circular disk or plate arranged radially of the axis and bolted to the outer edge of the peripheral part 7a2. At the center it has a bearing for the main shaft C.

Z is a shaft mounted in a bearing at /zf in the wall 7L* andA in a bearing /f in the Harige or bracket 7b3, and eZ' is a shaft mounted in a bracket at /ts and in the outer wall if.

C/ is a pinion on the crank-shaft C, engaged with a wheel D', keyed to the shaft d. D2 is a smaller wheel on this shaft, meshing with the wheel D3 on shaft rl, the last said wheel in turn meshing with the internal gearing at a3, secured to the drum.

The crank-shaft C is mounted in the bearings 2)', 7L', and 7L, it being jonrnaled directly in that at /L5 and being supported in the others through the medium of the hubs A A2 of the winding-drum, which are interposed between the shaft and the stationary bearings that is to say, the winding-drum and the shaft are mounted on the same axis, but are loose in relation to each other, so that they can turn independently either both in the same direction or, if it is desired, in opposite directions. The crank-disk C is by means of the wrist-pin c connected to the piston-rods e5 of the engine ele ment.

The shaft C is `provided with a brake mechanism,which may be of any suitable sort. As shown, a brake drum or wheel F' is keyed to the shaft, and with it are combined a frictionband and operating mechanism of any preferred sort.

The end wall la* is provided with a iiange or bracket H3, similar to that at B3, at the opposite end and adapted to be bolted to a framework, sueh as is conventionally illustrated at G. The two end sections or elements of the frame or housing are rigidly connected by girths or bracing-plates, such as at I, bolted to the peripheral parts Z22 and h2, so as to firmly join and brace them and prevent torsional strain or tendency to misplace one end of the frame in relation to the other. Such bracing or girding parts can be used around the periphery of the drum, and yet leave open or acoessible a sufcient part thereof to allow the rope to be readily wound and unwound.

Upon inspection of the drawings and from the above description it will be seen that I provide a winding mechanism and an operating mechanism, all of whose parts are compactly arranged and are so disposed as to provide a drum-like structure with incasing or housing walls which conceal and protect all of the operative parts. Consequently not only when the machine is stationary and in operation is there no liability to accident to operatives and no danger of breakage either of the parts of the apparatus or of other bodies in case the latter should accidentally come in contact with the moving parts, but, moreover and particularly, the whole structure becomes readily portable, and therefore adapted in a superior manner for certain special uses to which such a mechanism can be pnt. For instance, in mines, tunnel-work, operations in quarries, this is an excellent apparatus, because of its parts being' so designed and related that it can be readily moved from one place to another and as readily attached and detached from its frame G. Suppose, forexample, in operating a mine it is desired to move and control cars upon inclines or tracks of such grade that they cannot be readily transported or controlled by locomotives or horses. The present apparatus is available. The temporary frame or abutment structure is laid upon the ground, the hoistingapl'iaratus is secured thereto, as described, the rope is extended from the drum up more or less of the incline and around a suitable guide or sheave mechanism at the other end of the path of travel of the cars, and the free end of the rope is secured to a car or car-connecting device. rlhen the main duct for the steam or compressed air, such as a piping laid along the mine or tunnel, is connected by a hose or piping to the steam or air chamber and the mechanism is ready for use either to draw a car up the incline or to control it as it moves downward under the action of gravity. rlhen when the path of travel of the cars is to be varied-as, for instance, after the tunnel or mine-heading has been extended farther up the inclinekthe winding apparatus as a whole can be moved easily to a new position inasmuclr' as it is only necessary to release it from the framework at G and roll it over the ground or over a temporary track-like support, the peripheral parts at b2 if being then available as wheels upon which the whole mechanism can roll and be supported. \Vhen the new location is reached, an abutment-frame or holding structure G G is provided, and the winder is again fastened in place for a new series of operations.
